2001 l300 a/c
I need help folks! My A/C unit blower works fine. However, it won't heat or cool. The A/C unit does not deliver heat or cold but the blower works fine, has anyone else ever had this problem?

OK -- the blower motor has it's own separate fuse (different from the rest of the HVAC system), so we don't need to worry about it.
Look on the Engine Compartment Fuse Box (ECFB) -- find the fuse marked HVAC (40A), and make sure it's good. Then go inside the car, to the Left Instrument Panel Fuse Box (LIPFB) -- and find the fuse marked IGN3 (10A), and make sure it's good. Hopefully, that'll fix your problem, but if not, drop another note, and we will go further into this system .... |

Man, where the heck do you live that you're worried about the a/c this time of year? LOL

The L series cars have damper/cable problems. Check the damper operating cable behind the kick panel (drivers right foot) while operating the hot/cold lever.

OK -- I gotta ask you to do one thing, kindly take a picture of the HVAC panel in your car, and place it here on the thread. I'm suspecting a problem with the temperature control, but since there are two entirely different types of HVAC controls for that year, I gotta know which one you got. (slider arms, or rotary knobs)

The temp control is a rotary knob. |
